Also check pin post permission a bit earlier for the sender, with
canPost() in sendPinMessage(), even though there is a later check down
the line in dispatchMessage().
Fixes#4138
There were a couple of issues on how we handle pinned messages:
1) Clock of the message was only checked when saving, meaning that the
client would receive potentially updates that were not to be
processed.
2) We relied on the client to generate a notification for a pinned
message by sending a normal message through the wire. This PR changes
the behavior so that the notification is generated locally, either on
response to a network event or client event.
3) When deleting a message, we pull all the replies/pinned notifications
and send them over to the client so they know that those messages
needs updating.
This allows to store community admin settings that are meant to be propagated
to community members (as opposed to the already existing
`CommunitySettings` which are considered local to every account).
The first setting introduced as part of this commit is one that enables
community admins to configure whether or not members of the community
are allowed to pin messages in community channels.
Prior to this commit, this was not restricted at all on the protocol
level and only enforced by clients via UI (e.g. members don't see an
option to pin messages, although they could).
This config setting now ensures that:
1. If turned off, members cannot send a pin message
2. If turned off, pin messages from members are not handled/processed
This is needed by https://github.com/status-im/status-desktop/issues/5662
* add PinMessage and PinnedMessage
* fix gruop pin messages
* add SkipGroupMessageWrap to pin messages
* update pinMessage ID generation to be symmetric
